To all whom it may concern: j

Be it known that we, Enwoon Gsoss, WILLIAM E. Gnoss, and WALTER Fnn'rnn, citizens of the United States, residing at West Pittston, in the county of Luzerne and State of Pennsylvania, have invented a new and useful Pneumatic Cleaner, of which the following is a specification.

This invention has reference to pneumatic cleaners designed for removing dust and dirt from laid carpets, rugs and the like, and it is the object of the invention to provide an improved portable apparatus of this kind which can be easily operated, and which is eflicient in operation, the carpet,

etc, being thoroughly and expeditiously cleaned.

With these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinafter. described and claimed, reference being had to the accompanying drawing, in which drawing,

Figure'l is a longitudinal section of the apparatus. Fi 2 is a transverse section on the line 22 0 Fig. 1.

Referring to the drawing, 5 denotes .the casing inclosing the working parts of the apparatus. At the front end, and near the bottom thereof, the casing carries a transverse shaft or axle 6 on which are mounted ground wheels 7, said wheels being'fast on the shaft so as to impart a. rotary motion thereto when the casing is pushed across the floor, which is done by means of handles 8 connected to the sides of the casing, and'extending rearwardly therefrom. On the shaft 6 is mounted a cylindrical brush 9, which is fast on said shaft and turns therewith when it is in motion. Behind the brush 9 is located a beater comprising an arm 10 pivoted on a transverse shaft 11 carried by the side walls of the casing. ;One end of the arm has a horizontal bend 12 which comes and carried by the side walls of the casin On the tappet shaft 16 is a gear wheel 1 which is in mesh with a gear wheel 18 fast on the shaft 6, whereby the motion of the latter shaft is transmitted to the tappet wheel shaft to actuate the beater. Between the part 12 ofthe heater and the top portion of the casing, is interposed a coiled spring 19. When the tappets 14 engage the portion 13 of the beater, the part 12 swings upwardly, and compresses the spring 19, and

when the tappets clear said part 13, the

spring forces the part 12 of the beater downwardly against the surface of the parts to be cleaned, and a sharp blow is delivered there- A number of tappets are rovided in order that the blows 'may be elivered in quick succession.

Thetop of the casing 5 carries a fan casing 20 in which is mounted a rotary fan, the blades of which are indicated at 21, said blades being carried by a shaft 22 mounted in the end walls of the fan casing. On the fan shaft is a pinion 23 which is in mesh with a gear wheel 24 carried by a shaft 25 supported in one of the end walls 'of' the casing, said gear wheel 24 being in mesh with the gear wheel 18, whereby the motion of the shaft 6 is transmitted tothe fan shaft, and the fan is therefore operated when the apparatus is in motion.

In the rear portion of the fan casing 20, near its lower end, is an inlet comprising a short tube 25 to which a suction nozzle 26 is removably connected bymeans of an ordinary sli joint. 'The mouth of the nozzle is located ehind the beater, and extends close to the floor. Within the tube 25' is mounted a bag27 in which the dust collects, and

'from which it may be removed upon taking off the suction nozzle.

In operation, the apparatus is pushed across the carpet, rug or other part to be 7 cleaned. The motion im arted to the shaft 6 by the ground wheels is transmitted by the herein described earing to the tappetwheel shaft and the an shaft, so that the beater and the fan will be in operation when the apparatus is in motion, the brush 9 be- }ing also rotated. The casing 5 extends close to the floor, so that the escape of dust therefrom is prevented. The carpet, rug or other part is thoroughly cleaned by the beater and the brush, and all dust and dirt is sucked u by the nozzle 26, and passes into the bag 2 which, when full, may be removed and emptied u on slipping the nozzle off the tube 25. he apparatus is easily operated,

and is entirely automatic in operation, it

requiring no attention other than pushing it across the floor.

What is claimed is: 1. A cleaner comprising a casing, supporting wheels carrying sa1d casing, a shaft on which the wheels are mounted, a brush on said shaft, a beater located behind thebrush, a tappetwheel for operating the beater, a shaft carrying said tappet wheel, a gearing I between the t-appet wheel shaft and the first emcee brush, a tap et. wheel for operating the beater, a sha carrying the tappet wheel,

said shaft being o eratively connected to the first mentioned s aft, :1 fan casing carried by the aforesaid casing, a fan mounted in the fan casing, and driven from the first mentioned shaft, a tube extending from the fan casing, areceptacle mounted in the tube, and a suction nozzleremovably connected to the tube, the mouth of said nozzle being located behind the beater.

In testimony that we claim the foregoing as our own, we have hereto afiixed our signatures 1n the presence oftwo wltnesses.
